Fissure seam - Twisted Tunnels to max 6 (from 5)

[Nazey]

I think I've only done the Twisted Tunnels quest perhaps once in all my time in COR, it is just very rare that I happen to be level 5 and in a seam rather than doing the lowbie circuits.  I also vaguely recall that the quest was actually quite difficult for its level range.

The DM team will have numbers on whether this quest is getting any mileage but if it's not, perhaps bump it up to max 6?
